530516 - PBM Performance - .530" guide x 5/16" valve stem - High Temperature Seals
Our high temperature Viton seals offer superior oil control via a spring wiper. Seals will not get brittle and lose their ability to control oil. All seals are metal cased for positive fitment on valve guides. RS Series have a reduced outside diameter ideally suited for triple and double springs applications where clearance is a problem.
